SPECIFICATION forming part of Letters Patent No. 641,541, dated January16, 1900.

Appnmion tied october 15, 1598.

To @ZZ whom it may concern:

Be it known that I, CHARLES E. PIERCE, of Cambridge, in the vcounty ofMiddlesex and State of Massachusetts, have invented certain new anduseful Improvements in Heaters for Soldering-Irons, tbc., of which thefollowing is a specification.

This invention relates to heaters for portable articles, such assoldering irons, employing a burner for gas or other fuel, and a cockwhich controls the supply of fuel to the burner.

It is the object of my invention to provide means which will insure theclosing of the cock, either wholly or in part, when the heated iron orother article is being withdrawn from the burner, so that when theburner is not in use there will be no wasteful consumption of fuel.

The invention consists in the improvements which I will now proceed todescribe and claim.

Of the accompanying drawings, forming a part of this specification,Figure l represents a top plan View of a heater embodying my invention.Fig. 2 represents a section on line Fig. 3 is aview in perspective'illustrating my invention.

In the drawings, (referring for the present to Figs. l and 2,) crepresents a burner, which may be of the well-known Bunsen type and issupported by a suitable frame or holder b. c represents a cock whichcontrols the supply of fuel to the burner.

d d are rests located transversely within'a hood or heating-chamber I-I,said rests being provided with upwardly-extended beveled portionsdesigned to support the solderingiron e in position to be heated by theburner. The hood or chamber H is provided with an air vent or outlet Oin its top.

f is an arm or lever, which is pivoted at f to a platform or extension tof the holder b, said arm or lever being curved upwardly at fx andresting upon the inclined edges of the upturned sides t of said platformandin the path of the soldering-iron as the same is inserted into orwithdrawn from the position it occupies over the burner while beingheated. By this arrangement the inner end of said iron will strike thearm or lever j" and move the same outwardly, as indicated by dottedSerial No. 693,580. (No model.)

lines in Fig. l, said arm or lever also serving as a rest or support forthe handle of the iron while the latter is being heated. The arm orlever f is connected by means of a rod or link g with an arm h, aflixedto the cock c. The arrangement of the arm or lever f, cock c, and arm71. is such that when the said parts are in the position shown in fulllin/es in Fig. l the cock is opened to its fullest extent, so that afull supply of fuel passes to the b'urner. When the arm or lever f ismoved to the position shown in dotted lines, the vcock is closed, eitherwholly or in part,thus preventing waste of fuel when the iron is not inplace over it.

It will be seen that the arm or lever j' is moved to shut off the supplyof gas without any care on the part of the operator, and that when theiron is again inserted the arm or lever f may be pushed inwardly eitherby contact with the soldering-iron when the latter is beinginserted orby the operators hand.

c' represents a stop which limits the cockclosing movement of the arm orlever f, said stop being arranged so that the cock cannot be entirelyclosed, but will permit a small supply of fuel to pass to the burnerwhen the soldering-iron is removed, so that the burner is continuouslylighted. Y

In the drawings I have showna heaterlprovided with two burners and theaccompanying devices above described, it being obvious that any desirednumber of burners may be employed without departing fromthe spirit of myinvention.

From what has been said it will be observed that there is anoperating-arm connected with a gas-cock and arranged in the path inwhich the article to be heated is moved to and from the rest that issupported over the burner, so that in each case the cock is operated, ina certain sense, automatically-that is to say, the usual movement of thearticle to be heated, to and from its position on the rests operates thecock.

' I claiml. A heater of the character herein described, comprising asupporting-frame, a dome or heating-chamber supported thereby7 rests orsupports located within said dome or chamber, burners supported by saidframe below said rests or supports, cocks adapted to control the supplyof fuel to said burners,

arms or levers pivoted to said frame and having upwardly-curved portionslying in the path of the article to be heated and also serving as rests01' supports, connections between said levers and said cocks, and stopsdesigned to limit the movement of said arms or levers, substantially asset forth.

2. A heater of the character herein described, .comprising asupporting-frame having a platform or extension, a dome orheating-chamber supported by said frame, rests orsupports located Withinsaid dome or chamber, burners supported by said frame below said restsor supports, cocks adapted to control the supply of fuel to saidburners, arms or levers pivoted to said platform or extension and curvedto extend into the path of the article to be heated, said curvedportions also serving as rests orsupports, connections between saidlevers and said cocks, and stops on said platform designed to limit themovement of said levers, substantially as set forth.

In testimony whereof I have afxed my signature in presence of twoWitnesses.
